I'm having challenges with halflife 2 launching. I've installed steam and HL2 with no issues. But when I attempt to launch the game it gives me the "Preparing to launch HL2" window, then it disappears and nothing happens.
I'm running XP (sp2), AMD 1990 processor, radeon 9550 card, piles of ram and everything seems to be working ok except for HL2.
I'm also unable to run deathmatch...
I hope someone has encountered this and will be able to help me.
Thanks in advance
